ATTACHMENT FOR RUBBERS.

.SPEGIFICA'IlON-forming part of Letters Patent No. 506,142, dated October 3, 1893.

Application filed May 7, 1892. Serial No. 432.152- (No specimena) To all whom it may concern.-

Be it known that I, LEON J. WEATHERWAX, a citizen of the United States, residing at Aberdeen, in the county of Chehalis and State of Washington, have invented "certain new and useful Improvements inAttachments for Rubbers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to rubber shoes, and has for its object to provide an attachment therefor, of simple construction, which isdesigned to engage the heel of a boot or shoe to prevent the rubber becoming detached therefrom; and my invention consists in the construction and operation of such attachment, all of which will be fully and clearly set forth in the following description and specifically pointed out in the claims.

' In the accompanying drawings which form a part of this specification, Figure 1 represents avertical longitudinal section of a shoe and a rubber applied thereto and showing my improved attachment in connection therewith, and Fig. 2 is a View in perspective of the attachment detached.

The reference letter A denotes a shoe, the heel a of which is to be engaged by the attachment, and b is a rubber shoe of common construction. The attachment 0 which is socured in any suitable manner to the inside of the rubber,is constructed from a single strip of spring steel or other suitable material, which is bent. to form the arched portion a and the straight portion 0 which conform to the shape of the arched portion and heel of the rubber to which it is attached. The strip is bent over from the portion 0 to form a spring 0 which terminates in an upwardly projecting portion 0 This latter portion is bent over to form a tongue 0 which terminates in a series of serrations c which in operation engage the inner side of the heel and prevent the rubber from becoming detached therefrom. When the rubber is applied the lower inner edge of the heel strikes the face of the tongue and moves the same outward until the heel is in place. The attachment effectually holdsthe rubber to the shoe under ordinary conditions, but gives easily when the rubber is being withdrawn.

I claim 1. A rubber shoe having a rearwardly and upwardly inclined spring lever secured to the sole of the shoe forward of the heel portion, and having its upper free end adapted to be compressed by the inserted shoe to bear against the breast of the heel of the latter shoe, substantially as herein described.

2. An attachmentfor rubber shoes consisting of a single strip of metal having the arched portion 0, straight portion a and spring 0 having an upwardly projecting portion 0 terminating in a tongue 0 having serrations thereon for engagement with the inner'nd of the heel, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

LEON J. WEATHERWAX.
